Excellent.<quoted text> Human error decides whether there will be a failure. The design defines whether it fails safe. None of the mentioned designs had fail safe designs. The AP1000 approaches it more fully. Liquid Fluoride Thorium Recyclers can be made fail safe; not fail PROOF, fail safe.
There were design flaws involved in at least two of the three accidents I mentioned. What guarantee is there that design flaws won't be incorporated into ANY new design?
There is still human involvement, and humans make mistakes.
